Starting new job before quitting old

My start date for my new job is 6/24, and I'm wondering if I can stay at Google until the 25th (using vacation days for 24/25) because I have a chunk of stock vesting on the 25. Has anyone done this before?

There really are no good options for this. Never ever have an overlap of service dates unless you want to get possibly sued by Google in the future. I bet you are switching to another tech company and even if not, it would at least be considered moonlighting.

I did that with Microsoft in 2016. I gave ~2.5 weeks notice and Microsoft asked me to leave same day as I was joining Facebook. I started Facebook next Monday and got paid first 2 weeks from both Microsoft and Facebook. It felt nice 😊

If Google has a walkout policy, you can get paid from both places first 1-2 weeks ;)

Yes, above is correct in theory (you can get sued etc). In reality, it’s highly unlikely since it’s only a day overlap (unless you on some super “black ops” team ). More likely, you will be blacklisted and never work for google again

There will be no lawsuit. You can quit and use vacation days and make your last day after 1/2 weeks depending on PTO. Ask recruiter/HR/people ops. You aren’t allowed to work at both places. What you’ll do is handover laptop/badge access etc.
